vibration severity and vibration severity grade A
根据IEC 60034-14
The vibration severity is the RMS value of the vibration velocity
(frequency range from 10 to 1000 Hz). The vibration severity is
measured using electrical measuring instruments in compliance
与DIN 45666。
The values indicated refer only to the motor. These values can

轴高度20至132的振动严重性极限值
The speeds of 1800 rpm and 3600 rpm and the associated limit
values are defined in accordance with IEC 60034-14. The
speeds of 4500 rpm and 6000 rpm and the specified values are
defined by the motor manufacturer.
